The CD74HCT237 is a high-speed CMOS logic 3-to-8 line decoder/demultiplexer featuring address latches. It has three binary select inputs (A0, A1, A2) that can be latched by an active high latch enable (LE) signal, allowing for isolation of outputs from input changes. When LE is low, the device operates as a one-of-eight decoder. The product includes two output enable inputs (OE1 and OE0) to facilitate cascading and demultiplexing functions. The selected output is active high, which distinguishes it from similar devices in the series. This component operates over a wide temperature range of -55¬8C to 125¬8C and is designed for low power consumption while maintaining speeds comparable to low power Schottky TTL logic. The typical propagation delay is 13 ns at VCC = 5V, with a fanout capability of 10 LSTTL loads for standard outputs and 15 LSTTL loads for bus driver outputs. The CD74HCT237 is compatible with LSTTL logic levels, making it suitable for various applications in memory address decoding and data routing.
